General Description

The A1642 is an optimized Hall-effect sensing integrated circuit that provides a user-friendly solution for true zero-speed digital ring-magnet sensing in two-wire applications.

This small package can be easily assembled and used in conjunction with a wide variety of target shapes and sizes.

The integrated circuit incorporates dual Hall-effect elements and signal processing that switches in response to differential magnetic signals created by ring magnet poles.
